A flaw was found in Little CMS. An integer overflow in the `CubeSize` function within `cmslut.c` occurs because the overflow check is performed after the multiplication. An attacker could exploit this vulnerability by providing a specially crafted input, potentially leading to information disclosure or a denial of service (DoS), which makes the system unavailable to legitimate users.

Threats
Impact Moderate

A flaw was found in OpenJDK. The processImpl() method in SignatureFileVerifier exhibits O(n^2) time complexity when verifying JAR files where different entries have different signer combinations, potentially leading to DoS.

Red Hat / OpenJDK
cpe:/a:redhat:openjdk:25
Vendor Fix fix
Threats
Impact Moderate

A flaw was found in OpenJDK. When the software processes certain images, a specific function fails to manage memory boundaries correctly. This can lead to the application attempting to access invalid memory or dereference a null pointer, which may cause the application to unexpectedly terminate. The primary consequence of this vulnerability is a denial of service, making the affected application unavailable.

CWE-476 - NULL Pointer Dereference

Workaround
Threats
Impact Low

A flaw was found in OpenJDK. There exists a potential existential forgery vulnerability in CMS and protocols which use CMS. In Java, CMS is used to sign JAR files.

CWE-347 - Improper Verification of Cryptographic Signature

Product Identifier Version Remediation
Temurin Build of OpenJDK 25.0.4
Red Hat / OpenJDK

Vendor Fix fix
Threats
Impact Important

A flaw was found in OpenJDK. OpenJDK can apply two different security meanings to the same wildcard dNSName SAN across certificate policy enforcement and hostname verification. During path validation, DNSName.constrains compares *.foo.com and secret.foo.com literally and returns NAME_SAME_TYPE, so NameConstraintsExtension.verify does not reject the chain when secret.foo.com is an exact-host exclusion. Later, HostnameChecker interprets the same SAN as a wildcard template and accepts secret.foo.com for *.foo.com.
